Hello Garfield,
That rule about drone tracks is very funny indeed :) I will think about making something longer next time if I plan a drone track in future :)
In fact, this time I was more keen to make acousmatic composition in Parmegiani like style more than just drone and noise. Lately I am very passionate about his music and it influences me. This track turned out to be completely different from what I did earlier, you know. I want to try experimenting with such sound more in the future.
Anyway, thank you very much for your feedback. It's always nice to read reviews from different people - it stimulates the creativity!

Kind regards,
Igor
